Notes: Values are presented as mean ± standard deviation or n (%)
Fall risk score and cognitive screening score were questionnaire-derived summary scores and were analyzed as continuous variables; higher scores indicate higher fall risk and a greater number of cognitive-related problems, respectively
The cognitive screening score was used as a screening indicator rather than as a clinical diagnosis of cognitive impairment
P values were derived from one-way ANOVA or χ² test, as appropriate
